Note 4. Set n149 for the pulse train input scale to the pulse train frequency that is equivalent to the
maximum frequency (FMAX).
• The frequency reference set in n004 functions as frequency reference 1 when the Inverter is in multi-
step speed operation. The set values in n025 through n031 and n120 through n127 for frequency ref-
erences 2 through 16 are enabled.
H Selecting the Frequency Reference (n008) in Local Mode
• Select the input method of frequency references in local mode.
• Two frequency references are available in local mode. Select one of them according to the application.

Value Description
0 The settings of the FREQ adjuster in the Digital Operator are enabled. (See note 1.)
1 Key sequences on the Digital Operator are enabled. (See note 2.)
Note 1. The maximum frequency (FMAX) is set when the FREQ adjuster is set to MAX.
Note 2. The frequency reference can be set with key sequences while the FREF indicator is lit or with
the set value in n024 for frequency reference 1. In either case, the value is set in n024.
5-6-2 Upper and Lower Frequency Reference Limits
Regardless of the methods of operation mode and frequency reference input, the upper
and lower frequency reference limits can be set.
H Setting the Upper and Lower Frequency Reference Limits (n033 and
n034)
• Set the upper and lower frequency reference limits as percentage based on the maximum frequency
as 100%.
